Abstract
The invention discloses a machining technology of a cylinder barrel of a steering oil cylinder and belongs to the field of hydraulic oil cylinders. The machining technology comprises the main steps that of (1) blanking, (2) turning, (3) support welding, (4) milling, (5) drilling, (6) machining of an inner hole and (7) forming of a semi-finished product. In the step of support welding, the mode of semi-automatic welding with protection is adopted, the working efficiency and the machining precision are improved, and welding is safer. The step of inner hole turning and the step of honing are combined through a deep hole boring machine, inner hole turning and honing are conducted at the same time, the surface smoothness and the surface hardness of the inner hole are improved, and the errors of the inner diameter are reduced; besides, the procedure is simplified, and efficiency is improved.
Description
technical field
The present invention relates to a kind of processing technology of steering cylinder cylinder barrel, belong to hydraulic jack field.
Background technology
The processing of steering cylinder cylinder barrel, main employing following steps: blanking, turning, welding support, milling face, boring, car endoporus and honing, but this process has needs improvements, wherein welding support generally adopts the mode of human weld, pure human weld's efficiency is not high, and owing to controlling speed of welding artificially and unreliable, result in weld seam uneven; Car endoporus and honing are separately carried out in addition, and these two steps are separately carried out, consuming time on the one hand, result in machining accuracy on the other hand not high; And honing generally uses dry sanding paper, make inwall fineness not high, internal diameter also can be caused uneven.
Summary of the invention
Technical problem to be solved by this invention is: the processing technology providing a kind of steering cylinder cylinder barrel, it solves the low and problem that precision is not high of traditional handicraft efficiency.
Technical problem to be solved by this invention is taked following technical scheme to realize:
A processing technology for steering cylinder cylinder barrel, the processing technology of described cylinder barrel comprises following step:
(1) blanking: select cylinder barrel blank and pair of brackets blanking;
(2) turning: to blank roughing, turning, flat blank end face;
(3) welding support: two supports are symmetrically welded on cylinder barrel blank, use encircling welding equipment and gas shield welding manner, encircling welding equipment is the platform of a uniform rotation, cylinder barrel blank is fixed on platform, platform rotating speed can be set to 1r/min ~ 2r/min, gas shielded welding mode is welded for using carbon dioxide and argon gas mist, and carbon dioxide and argon content ratio are 4:1;
(4) milling face: use machining center carry out milling face to blank;
(5) hole: use machining center to hole to blank;
(6) interior hole machined: use deep hole boring machine synchronously to carry out car endoporus and Honing process to blank inwall, after processing, bore area smoothness requirements is Ra0.1 ~ 0.2(μm), case hardness requires increase by 20%, and internal diameter error is not more than 0.03mm;
(7) semi-finished product: to deposit etc. to be assembled.
The invention has the beneficial effects as follows: welding support uses the welding manner of semi-automatic band protection, improves operating efficiency and machining accuracy, and safer; Use deep hole boring machine car endoporus and these two steps of honing to be merged, synchronously carry out, improve bore area fineness, case hardness, reduce internal diameter error, and simplified flow process, improve efficiency.
